HRV Metrics Collinearity Analysis

Correlation matrix showing relationships between HRV features. High correlations (|r| > 0.8) indicate potential multicollinearity issues for predictive modeling.

Low HR Activity Collinearity

High HR Activity

High HR Activity Collinearity

Interpretation Guide

  • |r| > 0.9: Very high collinearity - consider removing one feature
  • 0.7 < |r| < 0.9: High collinearity - may cause issues in regression
  • 0.5 < |r| < 0.7: Moderate correlation - acceptable for most analyses
  • |r| < 0.5: Low correlation - independent features
